NO. 1581. FISHES OF JAPAN— JORDAN AND RICHARDSON. 655 



Habitat. — South Japan, north to Tokyo. 



Head 3.3; depth 4.2; D.IX-15; A.14; scales 57; eye 3.25; snout 2.2; 

 maxillary 2.3; interorbital space 3.75; first dorsal spine 1.4; second 

 dorsal spine 1.5; pectoral 0.6; ventral 1.0. 



Snout moderately emarginate, with a small secondary notch at 

 center, the angles without spine-like prominences; interorbital space 

 deeply concave; pre- and post- ocular spines little developed; a deep 

 postocular groove on each side; nuchal spine nearly to base of third 

 dorsal spine; opercular spine scarcely crossing gill opening; humeral 

 spine reaching past vertical from fourth dorsal spine; pectorals very 

 long, reaching to the eleventh or twelfth ray of soft dorsal; ventrals 

 past fourth anal ray; pectoral appendages short, the upper one 

 missing tip of ventral by a distance nearly equal to diameter of eye; 

 dorsal scutes moderately developed, with broad, flattish (not spine- 

 like) points. 



Preserved specimens show a rather sharp line separating the upper 

 (darker) part of side from the lower silvery portion; spinous dorsal 

 with a diffused blotch between the fourth and seventh spines, and 

 with more or less dusky shade forward, especially near margin of fin ; 

 soft dorsal \\dth cross rows of faint dusky spots; pectoral black inside, 

 with scattered lighter spots; pectoral appendages with some dark 

 pigment midway of their length. 



(japonicus, Japanese.) 



The long pectoral fins of tliis species separate it unmistakably from 

 the other species of Lepidotrigla found in Japan. 



Specimens have been examined from the following localities: Naga- 

 saki, market, 1 specimen, 4 inches (1906); Misaki, 1 specimen, 4^ 

 inches; Wakanoura, 4 specimens, 3 to 4 inches. 



The above measurements were made on a Misaki specimen, 4^ 

 inches.

ChdidonichOiys Kaup, Archiv. f. Naturgeschichte 1873, p. 87 (hirundo). 



Scales small, no long shields along lateral line. 



Each dorsal fin \vith a series of spine-tipped sliields along its base ; 

 opercular spine small; dorsal rays IX-16; anal 15; anal spine want- 

 ing. This genus, like the next (Otohime) differs markedly from 

 Lepidotrigla in the smaller scales. From the closely related European 

 genus, Trigla, this genus differs in the unarmed lateral line. The 

 American genus, Prionotufi, has palatine teeth, these being wanting 

 in the old-world gurnards. Characters otherwise those of the family. 



The numerous species abound on the coasts of Europe, Africa, and 

 India; ranging north to Japan.
